Re: Question for mavman and others

Sounds like a Mid 10 second 1/4, not too bad.... But....

2 degrees of timing won't gain you too much. Most RPM heads I have seen those folks are running 34 degrees. Coming in full at 2500 is a good thing too. I thought they all had the bigger valves, not the 1.90?

Windsors like near 6000 for a shift point I had a 450 HP version for 8 years in 3 different cars, and that is always where it liked to shift.

If you think you should be faster....What stall and make is your converter? Maybe your slipping up top?

You probably have better the 500 HP. Maybe right on the edge of what a slightly modified C4 can handle. Do you have extra clutches in your drums? You would need 5 or more clutches in your forward drum. If you have 4 clutches, that is probably your issue.

Also, I would suggest (if you have not already) running with a wide band sensor on a few runs.. I bet your going rich up top....

Your low end sounds really good.
